STAMPING niviB 'aoInnRY-FORMS.

useful ImprovementsY in Stamping Eni-- broidery-Formgset vforth in the following specification.

rhis invention relates to embroidery forms and the manufacture thereof.

The object of the invention is to produce a tough, sufficiently stid embroidery formhaving the necessary flexibility and particularly one cheap and inexpensive to manufacture.`

The above and further obiects of the invention will better be understood by reference to the accompanying drawings which form a part hereof, in which like characters designate corresponding parts in the figures and toward which, as illustrative of the invention, the following specification is directed.

In the drawings Figure l is a diagrammatic representation of a press in which embroidery forms are being stamped; and Fig. 2 is a vertical section through line II-II of F ig. l but drawn to an enlarged scale and with parts broken away.

Heretofore it has been found necessary, when cutting embroidery forms out of sheet material through the medium of dies, to dust the operating faces of the dies with powdered soap-stone, otherwise the dies became clogged and great difficulty was experienced in removing an embroidery form without breaking its more delicate parts. This dusting with soap-stone was, vof course, necessary for each operation of the press. By practising my invention this time taking step is eliminated and, in addition, embroidery forms of stronger, more durable character are produced.

I start with a sheet or bolt of compacted fibers, preferably a sheet of compacted cot# ton felt. I form a solution of wax in a volatile solvent. I prefer to employ parafiin and gasolene, although I contemplate any suitable stiff wax such as beeswax and any of the volatile solvents such as the many in the hydrocarbon group. Then employing paraflin and gasolene I prefer to dissolve one pound of paraiiin in one gallon of gasolene.

This solution is then caused to saturate the 'sheet of vcotton felt which is subjected to pressure whilestill wet with gasolene under.

conditions permitting the evaporation, of the volatile solvent. For example, absorbent material may be situated on both sides of thesaturated' cottonv 'f elt when it is being subjectedtopressure. For some purposes I contemplate incorporating the paraffin into the cotton felt for less than its entire cross section, preferably from what is to be the top surface of the embroidery form downwardly to a more or less greater extent. Part of the advantages of my invention are attained with only a slight extent of the cross section being incorporated with the paraiiin. i

The pressure and, if necessary, heat is continued until all the volatile solvent is removed, when the finished body of embroidery form met# iai should Vbe cooled sufiiciently to soli the incorporated wax. A sheet 1 of this body fabric is then backed with straw-board 2. The surface 3 of the body fabric l, which is intended to form the top surfaces of the finished embroidery forms, is placed downwardly upon the cutting dies 4 usually mounted on blocks 5 `ance is indicated between the embroidery form 7 and the die 4, which actually takes place, the paraiiin serving lto effect a clean clearance of all parts of the embroidery form .from the die.

Although I have describedthe use of either paraiiin or beeswax, I contemplate the use of any material having similar properlties and likewise the use of any suitable volatile solvent for such filling material selected. However, I believe thatthe filling material employed should be waxy and substantially solid at normal temperatures but capable of flowing under heavy pressure. The term wax, as employed in the claims, is intended to embrace not only beeswax but other materials the equivalent thereoffor the urposes of the invention.
